With HamTV becoming active on ISS, orbital elements are now updated twice daily in /www.amsat.org/tle/ at 00:18 and 12:18 UTC. The intention is to have high quality TLE available to accurately calculate doppler shift for the 2.935 GHz downlink. Observations comparing these TLE to those that were caclulated based ephemerides and TLE produced by Johnson Space Center the last time HAMTV was active are desired, write jfitzgerald@amsat.org The following satellite has been removed from this week's distribution: VERONI ...Continue Reading
